OK this is an update January 2016, I found out that this is an Eva dual handle kitchen faucet. I also learned that Moen backs all their products 100%. I called them at 1800BUYMOEN and they.

Al Moen invented the cartridge faucet, and cartridge faucets remain a specialty of the Moen company. The company designs them to be removable so you easily can replace rubber gaskets and O-rings that may be causing leaks. Unfortunately, these rubber parts often stick to the valve housing and make removing the cartridge a challenging job. Moen sells a tool that makes pulling cartridges easier, but sometimes you need more help than that.
Cartridge Removal Procedure
The usual procedure for removing a cartridge is to unscrew the handle, and after turning off the water, pull out a retaining clip. In the best of circumstances, you then grip the cartridge stem with pliers and pull, and the cartridge should slide right out. In less than ideal circumstances, however, the cartridge won't budge, no matter how hard you pull -- and you begin looking for ways to gain more leverage. Before trying other pulling methods, however, it's wise to douse the cartridge with white vinegar and wait for an hour or two. It safely dissolves mineral deposits that may be binding it.

When the cartridge doesn't come out, even after treatment with white vinegar, you have occasion to make use of a tool that Moen manufactures for pulling stuck cartridges. The T-shaped tool fits over the stem and seats against the cartridge housing. After screwing its bolt into the cartridge stem, rotate the handle to loose the bonds holding the cartridge so you can pull it out. If the cartridge is old and stuck enough, however, you may end up pulling out the cartridge shaft and leaving the sleeve stuck in the housing. You need to remove the sleeve before you can insert a new cartridge.
![]() Pulling Out the Cartridge Sleeve
Plumbers confronted with a stuck cartridge sleeve have developed an effective method for removing it. You first cut threads into the inside of the sleeve with a 1/2-inch tap. The sleeve is made of brass, which is easy to thread. You then insert a 3-by-1/2-inch hardened steel bolt through the holes of three or four stacked 1-inch washers, and screw the bolt into the threads. When the bolt is deep enough so its head wedges the washers against the cartridge housing, tightening it with a wrench loosens the cartridge enough for you to pull it out.
Considerations
You don't always have to resort to a cartridge puller, especially when you're removing a cartridge from a sink faucet. Reattaching the faucet handle after you pull the retaining pin often gives you the leverage you need. Depending on the configuration of the faucet and wall or backsplash, you may be able to hook a pry bar behind the handle, support it against a piece of wood and pry the cartridge. It often takes only a small movement to break the seal so you can remove the cartridge by pulling on the handle.
